Features of panel radiators

General information

The main design feature of this class of heaters is the absence of traditional sections, instead front side made in the form of a solid panel. The latter is assembled from two steel sheets, which take the required shape as a result of pressing. In particular, channels for the coolant are stamped in them.

When two stamped plates are welded, a thin panel is formed, the thickness of which is hardly more than one centimeter. The radiator may consist of one or several such panels. Such a design provides many advantages, but at the same time, some disadvantages, which we will consider below.

Compared to traditional or bimetallic radiators heating, the capacity of steel panels is scanty. Due to this, fast circulation of the coolant is carried out in the heating system, and, as a result, almost instantaneous heating.

Already after 10 - 15 minutes panel heating heats up the room. However, this feature has a downside - the radiators cool down, in case the system is turned off, as quickly as they heat up.

In addition, an important feature of this design is air convection, although this only applies to radiators consisting of several panels. This opportunity implemented due to the presence of air channels located between the channels for the coolant.

As a result, the device heats up not only by radiation of thermal energy from the case, but also due to the circulation of thermal air in the room. Thereby Design efficiency can be as high as 75 percent.

However, despite the fact that panels for heating radiators are made of high-quality high-strength steel, they are designed to operate at low pressure in the system (no more than ten atmospheres) and coolant temperatures up to 110 degrees Celsius. For these reasons, they are usually used in private and multi-storey country houses.

Since in centralized systems heating pressure is above ten atmospheres, panel batteries are installed in apartments only in case of autonomous heating systems.

Note! It is impossible to use panel radiators in a centralized heating system, not only because of its high pressure, but also contaminated coolant. Narrow ducts quickly become clogged and the device fails. Therefore, to work in such conditions, it is better to use bimetallic radiators.

Advantages

There are quite a few advantages for batteries of this type, below are the main ones:

Neat, simple enough, but at the same time stylish design. Moreover, modern equipment, which is used in the manufacture of these devices, allows you to produce products in different styles, ranging from classic to minimalism.
The ability to adjust the degree of heating of the device, due to the fact that products, as a rule, are equipped with all kinds of electronic or mechanical devices.
Increased heat transfer - as mentioned above, the use of the principle of convection can significantly increase the level of efficiency.

The price is much lower than other types of batteries. This is due to the fact that steel itself is much lower than copper and aluminum.
Profitability - since the devices have a small capacity, much less energy is spent on heating the coolant.
Multifunctionality - the device performs the function of both a conventional radiator and a convector.
Light weight, making it easy to install batteries yourself.
Possibility to choose the most suitable device suitable sizes and required power.

Advice! You can give the appearance of panels and ordinary sectional batteries, for example, cast iron, by installing special panels. Moreover, this can not only make them more attractive, but also more effective. Panels for heating radiators can be made from the most different materials such as wood or metal.

disadvantages

With all the advantages of these heating devices, they cannot be called ideal radiators for the following reasons:

Susceptibility to water hammer - this is one of the main reasons why panel batteries cannot be used in centralized heating systems.
Sensitivity to the level of water acidity - in order to avoid corrosion of the steel surface, the pH level of the coolant must be stable and kept in the range of 8.3-9.5.
The operating instructions for panel batteries prohibit draining water from the system for a long time. Otherwise, the internal steel walls of the structure will come into contact with oxygen, which will lead to corrosion.

For these reasons, it is far from advisable to purchase panel radiators in all cases.

Types of panel radiators

All existing steel panel radiators are divided into several groups.

In particular, according to the connection method, they can be conditionally divided into two types:

Devices with bottom connection– both battery pipes are located at the bottom. Such a connection is convenient in cases where they pass through the floor. True, it should be borne in mind that in this case the heat loss coefficient is quite large.
With lateral connection - in this case, the inlet pipe is located on top, and the outlet pipe is located below. This ensures uniform heating of the heating device. True, if the structure has many sections, then in this case significant heat losses will occur.

As mentioned above, the radiators in question may differ in the number of panels. On this basis, they are classified into the following types:

Advice! Knowing the types of radiators, it will not be difficult to correctly select heating devices, in accordance with the area of \u200b\u200bthe heated room.

Also, the devices differ in size, which can be as follows:

Width - 40 - 300 cm;
Height - 30 - 90 cm.

Therefore, before purchasing devices, it is necessary that they depend on the area of \u200b\u200bthe room and the power of the system.

Manufacturers of panel steel batteries

As you know, the quality of batteries depends not only on the type of design, but also on the manufacturer. Therefore, you should not give preference to the cheapest products from little-known manufacturers. An insignificant benefit can lead to the fact that soon you will have to change radiators with your own hands.

Buderus (Germany);
Thermoplus (Italy);
Lideya (Russia);
Kermi (Germany), etc.

In addition, products should be purchased at large hardware stores in order to avoid counterfeiting and be sure that the seller fulfills the warranty obligations.

Conclusion

Panel steel radiators have a number of advantages over analogues, however, it should be borne in mind that their use is limited by some technical specifications. If the conditions in your heating system meet the requirements of these devices, then they will be an excellent choice.

How are panel radiators installed?

Today, there are several basic connection schemes, two of them are used for side-connected batteries and one is used for bottom-connected batteries.
Therefore, calling up the installer of heating equipment, be sure to report how the heating system is arranged or how you plan to install it.

Lateral diagonal connection - allows for maximum heat transfer, which is why for many it is the most preferable. The use of this option implies connecting the supply pipe to the upper pipe of the radiator, and the outlet pipe to the lower pipe on the opposite side of the device. In this case heating appliances deliver their maximum power. The technique is great for long radiators and promotes uniform heating.
One-way (side) connection is most often used in high-rise buildings. This technology involves connecting the supply and return on one side, the supply pipe is connected to the upper pipe, the return is connected to the lower connection on the same side. The efficiency of this method is high, but slightly lower than when using the previous method.
The bottom connection of radiators is very popular today. Use this method during the pipeline in the floors. The heat transfer of devices when using this method is also slightly lower than when using a diagonal circuit.

The choice of battery connection scheme depends on many factors, determine the most suitable option in terms of technical and engineering features of the premises, only a professional can. The master will make not only a technical calculation, but also a project for the future heating system.

Buderus Logatrend panel radiators are used in one-pipe and two-pipe systems.

Logatrend K-profil are available for side connection, the devices have 4 nozzles (2 on both sides from the top, two from the bottom on both sides, diameter internal thread 1⁄2 inch holes). Models do not have mounting brackets, so the side does not matter during installation. You can install heaters on the wall or on the floor, for the first option you will need a classic mounting kit, and for the second you need a special stand bracket.
Logatrend VK-profil are available with bottom connection and two spigots with 3⁄4" male thread. The radiators of this series come without mounting brackets, so during installation they can be turned to either side, the connection node, depending on the selected side, will be either on the right or on the left side. The branch pipe for the inlet pipe is closer to the center, for the outlet pipe closer to outside corner. You can mount the devices on the floor, or you can install them on the floor using special brackets.

The devices have the ability to adjust the intensity of heating, for this purpose electronic and mechanical devices are used - thermal heads. Professional craftsmen will select equipment, pipes and components, install heating systems and carry out all necessary work associated with the installation of heating equipment.

Do-it-yourself radiator installation: the main mistakes of homeowners

Almost 90% of homeowners' complaints about poor heating have the same cause - not correct installation batteries. Mounting and connecting heating equipment is a simple process that requires consistency and compliance with the manufacturer's recommendations.

Most popular mistakes:

Installing the device below the prescribed level. Such an error leads to a significant decrease in heat transfer.
Installing appliances higher than they should reduce the flow of warm air.
Use of racks for floor mounting made by other manufacturers, not suitable in size. It is recommended to use components from the same manufacturer as the radiators themselves.
Not horizontal installation of devices.

If you plan to install the radiator yourself, carefully read the manufacturer's recommendations for installing and connecting devices.
Experts recommend not to take risks in this case, and if you have even a drop of doubt, use the services of a professional installer who will perform all the work from and to and provide a guarantee.
